I've listened to all 4 surround mixes on the blurays, and I really enjoyed them. I admit I couldn't play anything loud as my wife was working at home, and I'm off work sick so I wasn't taking it all in! The fidelity of them is excellent and the surround mixes I would say are subtle and appropriate, without being gimmicky. And the music is timeless, original and amazing. Hopefully I'll get a chance for another few listens over the next couple of days.
The box is a thing of beauty. Very sturdy and heavy and well put together. The book included is such good quality, thick pages and loads to look at and read. There doesn't seem to have been any skimping in making this set, and the price they are charging for it is such good value compared with sets like All Things Must Pass and Let It Be. Excellent stuff.
